Multipath Parameter Estimation and Channel Prediction for Wideband Mobile to Mobile Wireless Channel
نویسنده
چکیده
In this paper, we investigate the estimation of multipath parameters and prediction of wideband multipath fading channels for mobile-to-mobile wireless communications. Based on a statistical model for mobile to mobile urban and suburban channels, we derive a parametrized model and utilize two-dimensional ESPRIT algorithm to jointly estimate the delay of arrival (DOA) and effective Doppler frequencies of the dominant paths from noisy channel observations. The parameter estimates are then used in the model to predict future states of the time-varying and frequency selective mobile-to-mobile channel. Simulations were performed to evaluate the performance of the prediction scheme and results show the potential for long range prediction in doubly selective mobile to mobile channels. Key–Words: Multipath fading channels, wideband mobile-to-mobile channel, parameter estimation, ESPRIT, channel prediction
